Visual Studio Code - tslint - pattern matcher - visual-studio-code

Question

I tried to implement the pattern matcher for tslint but it is going haywire. I am certain that regex is specified correctly, yet VSC keeps highlighting incorrect files. Here is my tasks.json file:
{
"version": "0.1.0",
"command": "gulp",
"isShellCommand": true,
"args": [
],
"tasks": [
{
"taskName": "build",
"args": [],
"isBuildCommand": true,
"problemMatcher": [
{
"owner": "gulp",
"fileLocation": ["absolute"],
"pattern": {
"regexp": "^\\[[^>]* > ([^(]*)\\((\\d*),(\\d*)\\): (error) (.*)$",
"file": 1,
"line": 2,
"column": 3,
"severity": 4,
"message": 5
}
},
{
"owner": "gulp",
"fileLocation": ["relative", "${workspaceRoot}/src/"],
"pattern": {
"regexp": "^\\([a-z\\-]*\\) ([^\\[]*)\\[([\\d]*), ([\\d]*)\\]: (.*)$",
"file": 1,
"line": 2,
"column": 3,
"severity": 1,
"message": 4
}
}
]
}
]
}

Answer 1

Solved in version 0.2.0. It was a bug.

Answer 2

No only do you have to understand regular expressions, but you have to remember to escape for json too!
To get this working from the straight output from tslint rather than the gulp version, I had to use:
^(.*\.ts)\[(\d+), (\d+)\]: (.*)$
In the json this becomes:
"problemMatcher": {
"owner": "tslint",
"fileLocation": [
"absolute"
],
"severity": "warning",
"pattern": {
"regexp": "^(.*\\.ts)\\[(\\d+), (\\d+)\\]: (.*)$",
"file": 1,
"line": 2,
"column": 3,
"message": 4
}
}
